c# - Updating label content within a method -

i need change wpf label content within process, tried no content change in real time. doing wrong?

event caller:

private void connect_button_mousedown(object sender, mousebuttoneventargs e) {     mouse.overridecursor = cursors.wait;     labelststusupdate("connecting.."); // status changer     config = new configuration();     bool status = config.connectviausb();     mouse.overridecursor = null;     if (!status)     {         labelststusupdate("disconnected");// status changer     }     else     {         labelststusupdate("connected");// status changer     } } 

status changer method:

private void labelststusupdate(string message) {     dispatcher.begininvoke(dispatcherpriority.background, (sendorpostcallback)delegate     {         available_amount_label.content = message;     }, null); } 

this code recent application changing value of label in runtime try find workaround this

 public partial class mainwindow : window  {   int value=0;   private delegate void updatemylabel(system.windows.dependencyproperty dp, object value);    private void processmerge()   {      updatemylabel updatelabeldelegate = new updatemylabel(_mylabel.setvalue);       foreach (var item in collections)      {             string _mylabel= "process completed..." + value.tostring() + " %";             dispatcher.invoke(updatelabeldelegate, system.windows.threading.dispatcherpriority.background, new object[] { system.windows.controls.label.contentproperty, _mylabel});         value++;      }   } }   }
